IMPROVEMENT IN CHlMNEVi-COWLS.

Specification forming part of Letters Patent No. 142,909, dated September 16, 1873 3 application filed July 22, 1873.

To all whom 'it may concern:

Be it known that I, GEORGE HENRY GAR- DERWINE, of Nokomis, Montgomery county, Illinois, have invented an Improvement in (lhimney-Gowls and I do hereby declare the following to be a full and correct description of the same, reference being had to the accompanyin g drawings, in which the figure represents my invention.

My invention relates to that class of chimney-cowls in which a cap revolves, and by means of a vane turns with the wind and keeps the vent in a proper position away from the storm.

It is found that by the wind constantly acting upon one and the same side of these revolving caps their journals and pivots become worn, and they become lopsided and iinally refuse to turn. To keep the revolving cap more evenly balanced, and to prevent this wear, is the object of my invention. To this end, therefore, my invention consists in providing the revolving cap with a counterbalancin g weight attached to its forward or Windward side, which counteracts the force of the wind and tends to prevent this wear.

A in the drawing represents the stove-pipe, which is provided with an upright spindle, C, secured in the stove-pipe by means of arms B riveted to the inside of said pipe. D is a cap,

constructed in diameter somewhat larger than the stove-pipe to be covered, and is closed at the top. In said top is a socket, g, into which the spindle C is to operate, and upon which the cowl turns. A collar, e, is also secured to the inside of said cap by means of arms E, riveted to the cowl in a similar manner. collar e rests upon a flange-shoulder, F, and is prevented from rising by the nut h. A vane, V Gr H, is riveted upon the top of this cap, and gives direction to its movements when the wind blows.

It is found in practice that the constant turning of the cap and the uneven weight of the vane, together with the force of the wind, soon wear the parts so that they bind one upon another and refuse to revolve, and the object of the revolving` cowl is entirely defeated. I therefore apply to the forward end H of the vane a oounterbalancing weight, I, guarded by the guard t', which weight has the eifect of keeping the parts more evenly balanced, and consequently producing less wear.

What I claim as my invention, and desire to secure by Letters Patentis- In combination with a revolving chimneycowl or cap a counterbalancing weight attached to the forward part to counteract the force of the wind, substantially as shown and described.

The above specification of my said invention signed and witnessed at Nokomis, this 18th day of July, A. D. 1873.
